title: Biliary elimination of non-steroidal anti-inflammatory drugs in patients.
abstract: In view of evidence in animals that enterohepatic recirculation of non-steroidal anti-inflammatory drugs contributes to small intestinal mucosal damage we have investigated the extent of biliary elimination of three nonsteroidals. Ibuprofen (n = 3), diclofenac (n = 2) and indomethacin (n = 3) were given to six patients with a percutaneous transhepatic cholangiodrainage placed in the bile duct system. One patient received all three drugs. The mean biliary elimination of ibuprofen was 0.82% of the given dose compared with 50.41% urinary excretion. When diclofenac or indomethacin was administered 4.62% and 6.40% of the dose were found in bile, whereas 34.73% and 32.22% (means) were recovered from urine, respectively. The mean percentage eliminated in bile as unchanged drug and active phase II metabolites was 0.15% for ibuprofen, 1.09% for diclofenac and 5.02% for indomethacin.
